Method hornerPolyR

JSAT/src/jsat/math/MathTricks.java:138–144

This evaluates a polynomial using Horner's method. It is assumed that the polynomial is stored in reverse order in the array coef, ie: from c n at index 0, and then decreasing. @param coef the polynomial with coefficients in reverse order @param x the value to evaluate the polynom

(double[] coef, double x)
